It's Friday Night in New Paltz. Naturally, I'm Philosophizing!!!!

So let's explore the lies in the film Watchmen, shall we?

Plato states in The Republic that people do not like being lied to. It causes them to be ignorant about what is actually going on. When people are ignorant about the situation at hand, they can't properly address an issue. It was portrayed in Watchmen that Dr. Manhattan was to blame for the nuclear destruction that occurred at the end of the film. When this lie was brought upon the people, they were relieved to find that it was not the Soviets, and they feared Dr. Manhattan's impending vengeance for their evils. If they knew the truth, the world would be at war. However, because Rorschach left his journal in the newspaper office, this may very well occur. People will hate “the falsehood”, and their souls will be deceived; they have been deceived into false peace. The type of ignorance one feels in their soul is true falsehood, and it is the worst kind of deception. It can be argued that this false peace is one of the worst kinds of deception, because peace is a serious issue.
Xenophon's Memorabilia is a defense of Socrates. He identifies Socrates' conversations, showing why Socrates is not guilty as charged. Certain actions of Socrates' were classified as unjust, such as his corruption of the youth and his advocacy against democracy. Xenophon defends that he thinks that this was beneficial to Socrates' students. Socrates was convicted, and drank hemlock, leading to his death. It is explored by Xenophon if Socrates deserves honor for this act (as we know, he could have chosen exile rather than death).
Rorschach gets put away in jail; unfortunately, this jail is full of criminals that Rorschach had brought to justice. An inmate attempts to murder Rorschach to get revenge, which leads to a huge prison riot. Nite Owl and Silk Spectre II break him free from jail, and he is able to continue his quest to find the real murderer and bring him to justice. Rorschach was framed for the murder; the justice system is lied to, thinking they have the actual perpetrator, when in reality, it was Veidt. This lie causes Veidt to still be on the loose, bringing evil upon humanity. While Rorschach was in custody, he was unable to bring Veidt to justice.
Rorschach and Socrates are both innocent men, convicted of crimes against humanity. Xenophon would probably defend Rorschach in this case. Rorschach was not acting unjustly; rather, he was seeking justice, and was falsely accused in the process, much like Socrates was apparently unjustly accused and convicted of crimes against the state. Unlike Socrates, however, Rorschach did not accept his fate; he broke out of jail and continued his quest. It's hard to tell if Xenophon would suggest that Rorschach is honorable; Socrates was honorable for accepting his conviction.
We are unaware of who Silk Spectre II's father is until Dr. Manhattan shows us that The Comedian raped her mother (Jupiter), and that it is he who is the father. When we learn that the comedian raped Jupiter, we receive an explanation between Jupiter, her daughter, and The Comedian. It shows us that the Comedian is a cold, disgusting person; a superhero that really isn't that super. It can be argued that he's a false idol; he is portraying himself as this grand person that is fighting for good, when in reality, he is harming human beings. Between the rape, the scene that takes place in Vietnam where he kills a woman, and the riot scene where he shoots people with the rock salt shotgun, it can be argued that The Comedian is a liar; he is portraying himself as a superhero, when in reality, he is a menace.
It is explored in Xenophon's Memorabilia of Socrates that lying is a part of man's nature, but however, it is unjust to lie. Someone who is defending justice, like all the “superheroes” in Watchmen, should not be lying. Euthydemus states that it would be strange for a person practicing justice to lie or be deceitful.
The Comedian has committed verbal falsehood. In this situation, it absolutely deserves hatred, as Socrates suggests liars do. Socrates begs the question as to if verbal falsehood is useful against enemies, or useful to stop those who are supposed to be friends; or those who out of madness, do something wrong. The Comedian committed many unforgivable acts out of madness. A lie, however, is not useful the way he had intended for it to be in these circumstances; The Comedian is maniacal, and his falsifications needed to be exposed for the greater good. Plato suggests that lying is best left up to specialists, or that lying should be used as medicine by the ruler of a municipality; obviously, The Comedian is no specialist, nor is he the ruler of the city. He is indeed an ordinary person, as due to his maniacal actions, can not be thought of as a hero.

Whew.
